To all whom it 'may concern:

Be it known that I, NILs Fenomeni AM-v nURsEN, of Newton, in the county of Middleand State of Massachusetts, have invented certain new and useful Improvements in Carts for Distributing Concrete, &c., ofwhich the following is a specification.

.This invention has for-its object to'provide a cart adapted 'to be conveniently loaded with concrete or other like material at a central or receiving point, and to trans-Y ,wheels at opposite sides olfthe cart without f liability of being deposited in'the path of the wheels, means being provided whereby the operator standing on the supporting trame, may open and close the outlet, and may propel the cart in either direction, so that after the cart is loaded, it may be propelled to any point `more or less distant from the loading` oint, -where its contents may be discharged.

Of the accompanying drawings forming la part of this s'pecilication,-Figure 1 represents a side elevation of a cart embodying my invention. Fig. 2 represents a rear elevation, portions of the frame being broken away in each of the views, and certain parts shown in section.

The same numerals of reference indicate the same parts in all the figures.v

My improved distributing cart comprises a supporting frame which in this embodiment of my invention is composed of paral-l lei I-beams 12,"suitable. cross bars connecting` said beams, and bearings 13 attached to the beams 12, the axles 14 l54 of the supporting wheels 16 17 being journaled in said bearings. 18 represents a hopper mounted on the supporting frame, and suitably aflixed thereto, the hopper being oit-tapering form and enlarged at its upper portion, and

contracted at its lower portion, the latter extending downwardly between the I-beams 12, and being provided at its lower portion with a discharge outlet'20 and with a gate 2l which is hinged at 22, and is adapted to close the outlet. The supporting freine is provided with a platform V23,.cons`u t l' D a support or station fo' an operatorp id supportbeing preferablyl located at one end of the frame.

Loeatedin suitable operative proximity to the support 23 are levers 2l and The lever 211s fulcrumed at 2b' to the supporting frame, and the lever 25 is inlerumed on the axle 15. Said lovers are so arranged' that they may be operated byv a person standingon the platform (ir-support E23; The lever 24 is connected by .a rod 27 with the gate A21, and is adapted to be locked in the position shown in Fig, l by suitable means, such as a dog 2S carried by the lever` and one or more ratchet teeth 2l) alhxed to the platform.

Patented Aug. 31, 1909.

When the lever is thus locked, itiholds the A gate 21 closed. 'When the lever is released it permits the gate to swingopen under the pressure against it of the charge ot' 'material in the hopper. When the gate is opened, the material slides down the inclined bottom otthe hopper, and is delivered between the wheels at opposite sides of the cart. wheels preferably run on tracks 30, which 'are .located at opposite sides of forms which constitute a caritylfor the reception of a mass of concrete, the forms 31 molding the concrete deposited between them into a wall or other structure. The. tracks 30 extend parallel with and at opposite sides of the form 31, thearrangement heiligv such that the` material.- discharged from the hop er through the opening- 20, enters and is istributed in the cavity according to the position ofthehopierat the time of the discharge. The lever l25 lorms a part of a propelling mechanism adapted to move the `cart along the tracks. Said mechanism includes a gear 32 allixed to the axle 15, and a double-pointed or reversible ratchet 33 pivoted to the lever. 25, and adapted to engage the teeth of the gear 32 in either of two Said ositions, so that the gear may be rotated 1n one direction by an upward movement of the lever, when the dog is in the position a mixing apparatus, the gate 21 being locked to retain the charge in the hopper. The opeiator then by manipulating the lever 25, propels the cart to the point Where the load is to be discharged. and then 4by manipulat- 'ing the lever 24, releases the gate, and per* The gate mits.the-diseharge ol the load.

vmay then be closed, and the cartl propelled in the 'opposite direction back to the starting point. l

- Giving to the fact that; the discharge outlet is laterally contracted, although its loiver end is above the horizontal plane of the lo\v.

yermost portions 'ot the'ivheels, the material discharged is practically preventedfrom heing so deposited as to lie inthe `path of the wheels. As shoivn in Fie'. 2, the material ivill drop directly into the `forni 3l. It the hopper and the discharge outlet therefrom were ot' such lateral dimensions as to any where nearly 'approach the spare between the ivheels, the material ivould almost eertainlylbesii-deposited as to result in derail- 4'ing the cart.4 lliisis ot especial advantage '.yvhere the cart is to be propelled both for- .i'vilrd and back 'ard by an operator riding thereon, particularly tor the special purpose described which requires a number ottrips back and forth on the tracks or rails in order to fill the form 3l. The position of the lower end of the hopper above the bottom of 'the wheels, enables the cart to be used in the manner above mentioned, viz., {o lie loaded at; one point and then moved to a more or less distant location where the lill is to be `made.

""f-ItP will be seen that by providing a supyand having provisions for port for the operator, and gate-operating and propelling,r mechanism having members such as the levers 2i and 25 located in o erative proximity to the support so that tiey may both he manipulated by an operator vstanding` thereon, the cart is adapted to be vmember operatively related to said support.

9. A distril'nitinal cart comprising a livheeled supportingl` `traine having' a support, tor an operator` a hopper mounted on the iranie,`and ha ving a laterally contracted discharge outlet, a gite adapted to close the outlet, means for locking and releasing said gate, and mechanism for propelling the cart, said mechanism includin an operating member operatively relate to said support propellingthe cart in either direction.

ln testimony whereof I have atlixed in v signature, in presence of two witnesses.
